要应用 Parameter 特性,说明它是一个组件参数,在 component 标记帮助器中可以传参。 2、把 RouteView 组件放到 CascadingValue 组件下面,并让它的值(Value)引用 Version 属性的值。 // App.razor 文件<RouterAppAssembly="@typeof(App).Assembly"><FoundContext="routeData"><CascadingValueName="ver"TValue="stri...
Pass data into a RenderFragment to give it context. Use a CascadingParameter to pass the parent TabControl component into its child TabPage components. 下面看最终效果图: 实操开始: 请先创建一个Blazor项目(Blazor Client或者Server皆可,我们以Blazor Server为例), 第一步,创建两个组件:TabControl和TabPage。
bUnit is a testing library for Blazor components that make tests look, feel, and runs like regular unit tests. bUnit makes it easy to render and control a component under test’s life-cycle, pass parameter and inject services into it, trigger event handl
It renders the layout and passes it the type of the component to add to theBodyRenderFragment. 组件 所有的组件都是普通的实现了IComponent接口的类。 IComponent接口的定义如下: public interface IComponent { void Attach(RenderHandle renderHandle); Task SetParametersAsync(ParameterView parameters); } ...
Avoid the use ofcatch-all parameters. If catch-all parameters are used, every explicit parameter onDynamicComponenteffectively is a reserved word that you can't pass to a dynamic child. Any new parameters passed toDynamicComponentare a breaking change, as they start shadowing child component param...
Razor components work in a similar fashion, although the component properties must also be marked with the [Parameter] attribute to be considered component parameters.The following Counter component defines a component parameter called IncrementAmount that can be used to specify the amount that the ...

在组件的代码中,使用[Parameter]属性的SetParametersAsync方法来设置自定义范围输入参数的默认值。例如,可以在组件的OnInitializedAsync方法中设置默认值。 下面是一个示例代码,展示了如何在Blazor上将自定义范围输入传递为默认值: 代码语言:txt 复制 // MyComponent.razor @using Microsoft.AspNetCore.Components 最小值:...
不用[Parameter],我们可以这样用[CascadingParameter]: [CascadingParameter] public int MyParameter { get; set; } To pass a value to the component, we surround it with a CascadingValue component like this: <CascadingValue Value="MyProperty"> ...
